Abstract: With the interest-driven and patriotism-driven college students' mass incidents as the research focus, this paper probes into the psychological and behavioral patterns underlying college students' involvement in collective actions in mass incidents in China. The paper also investigates the college students and student management staff from Beijing, Chongqing and Guangzhou. The results suggest that the generative mechanisms of the two types of college students' mass incidents and the function pathways of their integrated models are slightly different. In interest-driven mass incidents, national identity, school identity, and information dissemination produce impacts on behavioral intention via group efficacy pathway. In patriotism-driven mass incidents, national identity, triggering event cognition and information dissemination produce impacts on behavioral intention via group-based anger pathway. Both triggering event cognition and information dissemination produce significant impacts on group-based anger in either type of incident. Through studying college students in the background of China, this paper has thereby expanded Social Identity Theory (SIT) and Dual-Pathway Model's application in mass incidents.
